SPEQIFICATION forming part of Letters latelit N0. 772,508, dated October 18, 1904. Appleman nea June 6, 1904. serai No. 211.326. (No model.)

To all whom it may concern.

Be it known that we, SALUTHIELV. GRAVES and ABsALAM F. FRY, citizens of the United States, residing at Bentonville,in the county of Benton and State of Arkansas, have invented certain new and useful Improvements in Dust-Sprayers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in insect-'destroyers or powderdusters; and the object of the invention is to generally improve upon and render more efflcient this class of inventions, and to that end we provide various details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically delined in the appended claim.

Our invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal central section through lour improved powder-cluster or insect-destroyer, and Fig. 2 is a top plan view.

Reference now being had to Vthe details of the drawings by letter, A and A designate,l respectively, the top and bottom portions of a bellows forming a part of our' apparatus and which are disposed at angles to each other, and resting upon the portion of the bottom A' which projects beyond the end of -the top A is a box or receptacle B, adapted to contain powder to be sprayed or blown by the draft coming from the bellows. Leading from said boX is a pipe C, which may be provided with'detachable nozzles of any diameter or size desired. Hinged to the bottom' B of said'receptacle is a partition D, which has a swinging movement limited by the top and bottom of said bellows. To the marginal edges of said top and bottom of the bellows and to the marginal edge of said swinging partition is fastened an inclosingfabric of leather or other suitable material, thus making two air-tight compartments, one upon either side of the'central swinging hinged partition. In the bottom of said boX is an aperture b, whereby-communication may be had between'the receptacle and the space intermediate the hinged partition D and the bottom A', and a valve is positioned over said opening?) and allows airl to enter the receptacle from the lower section of the bellows, but is closed whenY the lower section of the bellows is drawing in air through an aperture c', formed in the bottomV A. Said aperture c is provided with a valve a?, whereby the air which has been drawn into the lower section of the bellows when the partition D is raised will be prevented from escaping through the aperture a when the partition D is thrown toward the bottom A in the act of forcing air which has been drawn into the lower section of the bellows through the aperture Z3 into 'said receptacle B. The upper portion of the bellows, intermediate the hinged partition D andthe topV A, has a communicating aperture E between th'e same and the receptacle B and also has an inlet-aperture c, which is formed in the tp A and is regulated by a valve c3, which allows air to enter but not to make exit from the upper section of the bellows.

F designates a crank-shaft which is journaled at lF' in suitable bearings upon the top A and has a handle G at one end and has pivotal connection at /L with a link H, which is fastened to the projecting end of the partition D at H.

Fastened to the end of the boX B at K are the brace-bars N, which are fastened at N to the upper inclined face of said top A, and at points intermediate the .box and locations where said bars are fastened to the top ofthe bellows they are twisted, forming vertical and horizontal portions adapted to more securely brace and hold the parts secure. The ends of said bars N project beyond the outer end of the top of the bellows, being twisted a one-half turn. and have their ends at angles at O, where they are secured to the block Q, which is concaved upon its. outer face and adapted to rest against any object, such'as the leg of the operator or any other object, whereby the apparatus may be steadily held while being operated. Brace-rods S are secured at their lower angled ends to the bottom A of the bellows, and their upper ends, which are hooked, are caught into apertures in the vertically-disposed portions of the bars N, which project beyond the end of the bellows, as shown clearly in the drawings.

vThe top of the dust-box is provided with a suitable filling-aperture J, and any suitable means may be provided, if desired, for holding the different-sized nozzles upon the side of the box. Intermediate the vertical portions of said bars N, adjacent to the dust-box, is a handle P, which is fastened to said bars and which is adapted to be gripped by one hand of the operator, while the other hand of the operator is at liberty7 to operate the handle of said crank-shaft.

The operation of our apparatus will be readily understood, and as the hinged partition of the bellows is swung in opposite directions it will be observed that a constant draft of air is caused to be forced into the dust-box from the two sections 'of the bellows, thereby causing the material in the receptacle to be forced out through the nozzle and upon the bush or other object which it is desired to spray. While operating the apparatus the concaved portion of the block Q may be held against any portion of the body of the operator, while it may be immediately supported by the handle between said bars, while the other hand of the operator is at liberty to operate the bellows.

While we have shown a particular detailed construction of apparatus illustrating our invention, it will be understood that we do not limit ourselves to the exact construction shown, but may vary the same, if desired, without in any way departing from the spirit of the invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is*

An insect-destroying apparatus comprising a two-compartn'ient bellows with interlmidiate hinged partition, suitable valve-operated apertures leading to and from the compartments of the bellows, a receptacle supported by the bottoni of said bellows,wtlve-regulated apertures leading from each compartmentof the bellows into said receptacle, a pipe leading from said receptacle, bars fastened at their forward ends to said receptacle andsecured to the top of said bellows, a handle secured between said bars, and a body-engaging block fastened to the rear projecting ends of said bars, and braces fastened at their lower ends to thebottom of the bellows and at their upper ends to said bars, and means for operating the bellows, as set forth.

ln testimony whereof we hereunto allix our signatures in presence of two witnesses.
